Description

Technical Field

[0001] The utility model belongs to the technical field of silicon core tubes, and particularly relates to a silicon core tube with a temperature insulation layer. Background Art

[0002] Silicone-core pipe is a new type of composite pipe with a silicone solid lubricant on its inner wall. It is primarily used in optical cable communication network systems. Its core value lies in its inner wall coating with a silicone solid lubricant with an extremely low friction coefficient. Due to its excellent physical and chemical properties, silicone-core pipe has been widely used in communication network systems, municipal engineering, and other fields.

[0003] In the prior art, in the actual application of silicon-core tubes, when the temperature of the application environment changes greatly, if the temperature is too low, the material will become more brittle and prone to brittle fracture; if the temperature is too high, there will be a certain softening, thereby reducing the mechanical strength and pressure resistance of the silicon-core tube. Therefore, an insulation layer is usually set on the outside of the silicon-core tube. However, when the insulation layer is damaged at individual locations due to external force, the insulation effect of the insulation layer will be reduced, thereby affecting the performance of the entire silicon-core tube and having poor practicality.

One end of the support structure abuts against the outer wall of the inner tube, and the other end abuts against the inner wall of the outer tube.

[0014] In a possible implementation, the arc-shaped plate is inserted into the corresponding temperature-isolating channel and abuts against the outer wall of the inner tube;

[0015] There are multiple partition plates, and the multiple partition plates are arranged at intervals along the axial direction of the inner tube. One end of each partition plate is fixed on the arc plate, and the other end extends along the radial direction of the inner tube and abuts against the inner wall of the outer tube. The multiple partition plates are used to separate the temperature insulation channels to form multiple temperature insulation chambers.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] Please also refer to Figure 1 and Figure 2 The silicon-core tube with a thermal insulation layer provided by the present invention is now described. The silicon-core tube with a thermal insulation layer includes a silicon-core tube body 10 and a thermal insulation sleeve 20. The thermal insulation sleeve 20 is sleeved on the outer wall of the silicon-core tube body 10 and has multiple thermal insulation channels disposed therein. The multiple thermal insulation channels are annularly spaced around the axis of the silicon-core tube body 10. Each thermal insulation channel has multiple thermal insulation cavities disposed therein, and the multiple thermal insulation cavities are spaced along the axis of the silicon-core tube body 10.

[0027] Compared with the prior art, the silicon-core tube with a thermal insulation layer provided in this embodiment has a thermal insulation sleeve 20 arranged on the outside of the silicon-core tube body 10, and can be insulated by multiple thermal insulation channels arranged in the thermal insulation sleeve 20. Each thermal insulation channel is provided with multiple thermal insulation cavities. When the thermal insulation sleeve 20 is damaged at individual locations due to external force, the thermal insulation cavity at the damaged location can be isolated by the thermal insulation cavity, so that most of the thermal insulation effects remain unchanged, and the performance of the entire silicon-core tube will not be affected, which has good practicality.

[0028] In some embodiments, the above-mentioned thermal insulation sleeve 20 can be used as follows Figure 1 、 Figure 2 The structure shown. Figure 1 、 Figure 2 The thermal insulation sleeve 20 includes: an inner tube 21, an outer tube 22, a support structure 23 and a plug-in structure 24. The inner tube 21 is sleeved on the silicon core tube body 10 and abuts against the outer wall of the silicon core tube body 10. The outer tube 22 is sleeved on the inner tube 21 and is coaxially arranged with the inner tube 21, and an annular lumen is formed between the outer tube 22 and the inner tube 21. There are multiple support structures 23, and each support structure 23 is arranged at an annular interval along the axis of the inner tube 21. A thermal insulation channel is formed between any two adjacent support structures 23, the inner tube 21 and the outer tube 22. The plug-in structure 24 is located in the thermal insulation channel and is used to divide the thermal insulation channel into multiple thermal insulation cavities.

[0029] The inner tube 21 can be sleeved on the silicon-core tube body 10 and can serve as the first insulation layer of the silicon-core tube body 10. The outer tube 22 can be sleeved on the inner tube 21 and can serve as the second insulation layer of the silicon-core tube body 10. The annular tube cavity formed between the outer tube 22 and the inner tube 21 can serve as the vacuum insulation layer of the silicon-core tube body 10. The support structure 23 can be arranged in the annular tube cavity to divide the annular tube cavity into multiple insulation channels, and can also support the outer tube 22. The plug-in structure 24 can separate the insulation channels into multiple insulation cavities.

[0030] As a specific implementation of this embodiment, the cross-section of the support structure 23 can be a fan ring, which can be stably connected to the inner tube 21 and the outer tube 22.

[0031] In some embodiments, the support structure 23 may be formed as follows: Figure 1 、 Figure 2 The structure shown. Figure 1 、 Figure 2 Each supporting structure 23 is a rectangular plate and is arranged along the radial direction of the inner tube 21. One end of the supporting structure 23 abuts against the outer wall of the inner tube 21, and the other end abuts against the inner wall of the outer tube 22.

[0032] The supporting structures 23 are all rectangular plates, which can be understood as having one end abutting against the outer wall of the inner tube 21 and the other end abutting against the inner wall of the outer tube 22 , and can support the outer tube 22 .

[0033] As a specific implementation of this embodiment, the cross-section of the support structure 23 can be a fan ring, which can be stably connected to the inner tube 21 and the outer tube 22.

[0034] In some embodiments, the plug-in structure 24 may be configured as follows: Figure 1 、 Figure 2 The structure shown. Figure 1 、 Figure 2 Each plug-in structure 24 includes an arcuate plate 241 and a partition plate 242. The arcuate plate 241 is inserted into the corresponding insulation channel and abuts the outer wall of the inner tube 21. Multiple partition plates 242 are provided, spaced apart along the axis of the inner tube 21. One end of each partition plate 242 is fixed to the arcuate plate 241, and the other end extends radially along the inner tube 21 and abuts the inner wall of the outer tube 22. The multiple partition plates 242 are used to divide the insulation channel into multiple insulation chambers.

[0035] The arc-shaped plate 241 can be inserted into the corresponding insulation channel and abut against the outer wall of the inner tube 21, with a stable connection. The multiple partition plates 242 can separate the insulation channel into multiple insulation chambers.

[0036] As a specific implementation of this embodiment, the cross-section of the partition plate 242 can be a fan ring, which can be stably connected to the tube walls of the inner tube 21 and the outer tube 22.

[0037] In some embodiments, the arc plate 241 may be formed as follows: Figure 1 、 Figure 2 The structure shown. Figure 1 、 Figure 2 The arc-shaped plate 241 is integrally connected with the corresponding plurality of partition plates 242 .

[0038] The integral connection between the arc-shaped plate 241 and the corresponding plurality of partition plates 242 can be understood as the arc-shaped plate 241 and the corresponding plurality of partition plates 242 being integrally injection-molded.

[0039] In some embodiments, the arc plate 241 may be formed as follows: Figure 1 、 Figure 2 The structure shown. Figure 1 、 Figure 2 The arc plate 241 is provided with an arc surface that abuts against the outer wall of the inner tube 21.

[0040] In some embodiments, the partition plate 242 may be formed as follows: Figure 1 、 Figure 2 The structure shown. Figure 1 、 Figure 2 The cross section of the partition plate 242 along the axis of the inner tube 21 is a trapezoidal structure.

[0041] The trapezoidal structure can provide a buffer when the wall of the outer tube 22 is hit.

[0042] In some embodiments, the silicon core tube with the thermal insulation layer can be made of Figure 1 、 Figure 2 The structure shown. Figure 1 、 Figure 2 The silicon core tube with a temperature insulation layer further includes a silicone rubber layer 30 , which is arranged on the inner wall of the silicon core tube body 10 .

[0043] The silicone rubber layer 30 has extremely low static and dynamic friction coefficients, which enables the cable to be easily and repeatedly extracted from the pipe, greatly reducing the difficulty of construction and maintenance.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
